Ltd. Construction Project Overview
of Jiangxi Min'an Environmental Protection Consulting Service Co., Ltd.
Shangrao Zhongmin New Building Materials Co., Ltd. is located in Xiangtun Industry, Dexing City, Shangrao City, Jiangxi Province. The geographic center coordinates of the park are 117 ° 31 ′ 33.251 ″ east longitude and 28 ° 59 ′ 15.217 ″ north latitude. The project covers an area of 15000 square meters, with a total construction area of 7000 square meters. With emulsified asphalt, diesel oil, mineral powder and stone as the main raw and auxiliary materials, the project has formed an annual production scale of 300000 cubic meters of asphalt concrete by means of feeding, drying, grading and screening, powder lifting, weighing, mixing and feeding. The total investment of the project is 50 million yuan, including 1.78 million yuan for environmental protection.
Main environmental impacts and countermeasures and measures
to prevent or mitigate adverse environmental impacts 1. Strictly implement air pollution prevention and control measures
and adopt cleaner production measures to reduce waste gas production. According to the category and nature of the pollutants in the waste gas, the mature and reliable process is adopted to ensure the long-term stable discharge of the pollutants in the waste gas. The mixed waste gas from the asphalt drying drum of the project is discharged through an exhaust funnel with a height of not less than 15 m after being treated by a container-type air blowback bag filter (volute dust removal + bag dust removal), and the waste gas generated by the heat transfer oil boiler is discharged through an exhaust funnel with a height of not less than 8 m after being collected centrally. Asphalt fume is collected under negative pressure and then introduced into the main gas gathering pipeline for activated carbon adsorption + electric tar precipitator treatment, and then discharged through an exhaust funnel with a height of not less than 15 m; the mineral powder silo is provided with a dust collection hood and discharged after being treated by a bag-type dust collector; the discharge port of the project is fully closed, the feeding bin and raw material stacking are located in a closed plant, and the mixing process is closed. The emission standard of asphalt fume, asphalt line drying drum mixed waste gas and particulate matter shall comply with the limit requirements in Table 2 of the Integrated Emission Standard of Air Pollutants (GB16297-1996); the odor emission shall comply with the limit requirements in Table 1 of the Emission Standard of Odor Pollutants (GB14554-93); The exhaust gas from the heat-conducting oil furnace shall be subject to the limit requirements for oil-fired boilers in Table 2 of the Emission Standard of Air Pollutants for Boilers (GB13271-2014); the emission of oil fume from canteens shall be subject to the Emission Standard of Oil Fume from Catering Industry (Trial) (GB18483-2001).
2. Strictly implement water pollution prevention and control measures
, and reasonably formulate wastewater collection and treatment schemes in accordance with the principle of "clean water and sewage diversion, rain and sewage diversion, quality treatment and multi-use of water". The vehicle washing wastewater is recycled after being treated by the sedimentation tank and is not discharged; the initial rainwater is reused for sprinkling and dust suppression in the plant area after being treated by the rainwater sedimentation tank; The domestic sewage of the project is discharged into the sewage treatment plant of Xiangtun Industrial Park in Dexing City through the sewage pipe network of the park after being treated by the septic tank to meet the standard of Grade I B in the Discharge Standard of Pollutants for Urban Sewage Treatment Plant (GB18918-2002), and then discharged into Le'an River.
3. Strictly implement noise pollution prevention and control measures
. Noise mainly comes from the operation noise of mechanical equipment such as mixing system, drying, heating and lifting system. The plane layout of the plant shall be optimized, low-noise equipment shall be selected, and sound insulation, noise elimination, sound absorption, vibration isolation and vibration reduction measures shall be taken to ensure that the noise at the boundary of the noise source field meets the standard. The daytime and nighttime noise emission at the plant boundary of the project shall comply with the Class III standard of the Emission Standard for Industrial Enterprises Noise at Boundary (GB12348-2008).
4. Strictly implement solid waste pollution prevention and control measures
, strictly implement relevant procedures for hazardous waste transfer, and regularly entrust qualified units to dispose of hazardous wastes that cannot be comprehensively utilized. The general industrial solid waste produced shall be disposed of reasonably and shall not pollute the surrounding environment. The remaining asphalt concrete of the project will be recycled; the unqualified aggregate will be recycled by the aggregate supplier; the dust collected by the bag-type dust collector after drying the waste gas will be used as the raw material of asphalt concrete; the waste activated carbon, waste bags, waste engine oil, waste rags and waste oily gloves will be entrusted to qualified units for treatment; the domestic garbage will be collected and treated by the environmental sanitation department. Hazardous waste shall be stored in accordance with the Standard for Pollution Control on Hazardous Waste Storage (GB18597-2023).
5. Strictly implement environmental risk prevention measures.
Strictly implement various environmental risk provention and control measures, carefully formulate environmental risk contingency plan, and equip environmental emergency facilities and equipment. Once an environmental risk accident occurs, the environmental risk contingency plan must be started immediately to control and reduce the impact of external environmental pollution.
6. Strictly implement soil and groundwater pollution prevention and control measures. The storage, loading and unloading, transportation, production, pollution treatment measures and other links and processes of
raw materials and products shall be effectively controlled to avoid leakage and seepage of pollutants. At the same time, certain anti-seepage measures shall be taken for areas that may leak to the surface, and zonal anti-seepage shall be adopted for the plant area. Strengthen daily environmental management and strictly control the running, emitting, dripping and leaking of equipment and pipelines.
7. Planning requirements for project surrounding control.
According to the conclusion of the report table, the health protection distance of the project is 50m in the mixing plant and asphalt tank area, and 50m in the raw material workshop. Your company shall cooperate with the People's Government of Dexing City to strictly control the surrounding planning of the project, and no new residential buildings, schools, hospitals and other environmentally sensitive buildings shall be built within the health protection distance of the project.
8. Requirements for standardization of sewage outlet. Standardized pollutant discharge outlets shall be set up
according to regulations, and corresponding signs shall be set up. Waste water and waste gas outlets shall be provided with permanent monitoring and sampling ports in accordance with the requirements of monitoring technical specifications.
9. Establish and improve environmental management.
Strengthen the operation, maintenance and management of environmental protection facilities, formulate strict environmental protection post responsibility system, ensure the stable and normal operation of pollution control facilities, establish the operation account of pollution control facilities, strictly prohibit unauthorized idleness and suspension of environmental protection control facilities, eliminate accidental pollution discharge, and ensure that all pollutants meet the discharge standards. The
public participation
project has been accepted and publicized before approval, and no unit or individual has objected to the construction of the project.
